A global modeling study finds that adding vitamins and minerals to staple foods like salt and flour already reduces nutrient shortfalls at scale, with potential to expand impact at low cost.
A randomized clinical trial found high-dose vitamin D supplements did not reduce COVID hospitalizations or symptom severity, though researchers observed a small signal suggesting fewer long COVID symptoms among participants who took the vitamin.
New research shows specialized immune cells actively train the body to tolerate common foods such as corn, wheat and soy, offering clues that could one day help prevent food allergies.
A scientific review finds the popular supplement does not work like GLP-1 drugs and that its metabolic effects appear to depend heavily on the gut microbiome.
Researchers analyzing nearly 15,000 adults found that some antibiotics were linked to changes in the gut microbiome four to eight years after treatment.
Researchers found that matcha tea reduced sneezing in mice with allergy symptoms by dampening activity in a brain region that controls the sneeze reflex.
A large review of studies across 63 countries finds that food fortification programs consistently deliver major health benefits at very low cost.
A study finds that the balance of certain dietary fats can change the fat composition inside T cells, affecting their resistance to a form of cell death linked to immune function.
A new mechanistic study links specific microbes to higher peanut tolerance thresholds, but it does not change current medical guidance.
As celebrities and wellness influencers renew interest in unpasteurized milk, experts explain what we know about nutrition, allergies and bacterial risk.
New research links neighborhood deprivation to differences in gut bacteria tied to mental and metabolic health.

A global analysis suggests that little-studied microbes may help keep the gut ecosystem running smoothly across diets and cultures.
A small randomized trial suggests time-restricted eating may reduce inflammation and disease activity, but researchers urge caution and further study.
A large UK study links severe vitamin D deficiency to more hospital admissions for respiratory infections, though the findings show association, not cause.
A large UK study suggests routine inflammation markers, combined with diet patterns, could identify people at higher risk of relapse even when they feel well.

A randomized clinical trial finds short, monthly calorie restriction improved symptoms and inflammation markers in people with mild-to-moderate Crohn’s disease.
New research links waterfowl consumption to both omega-3 benefits and mercury exposure in northern Indigenous communities, underscoring the need for balanced monitoring rather than avoidance.
A new study traces specific bacterial strains from human milk to babies’ guts, offering insight into early microbiome development.
Research suggests certain proteins reduced bacterial colonization in mice, but findings do not replace medical treatment or clean water.
